I agree. MS shouldn't have been outrightly negative. How does a parent go from disliking his daughter to actively planning her kidnapping/murder? Why? Is he a psychopath?
Preferring a son over a daughter is one thing and trying to actively harm your daughter is another thing altogether.
They could've shown a few scenes where he's a little remorseful but is carrying out his tasks anyway, or is questioning Shashi's motives for continuously giving him outrageous tasks (since MS is supposed to be just a henchman, not The mastermind)
But he's getting more and more despicable with every episode with no insight to his psyche.
Koi toh reason hoga na?
